What's the best way to...

Maybe you should fix the wikipedia, the fix will stick since you've got a reference

Ok so the ww2 yak-3 could only do 650... but I can't hit 650 in BOP either. Seems to top out at about 550 for me. Low altitude, of course, could it go faster higher up? I've looked at e/m charts but not altitude performance charts

Right, the WW2 Yak-3 did 650 km/h, and later could do about 708 km/h with the VK-107. The WW2 Yak-3 best performance at high altitude, was maxed 10,300ft or so. The VK-105PF-2 wasn't much for high altitudes, and could freeze up if at certain altitudes. (More like B-17 altitude etc. I would guess.) Its max ceiling was like 35,000ft but it performed terribly due to its wingspan and all around small body etc. Anyway, I would try it around 10,300ft and see what you get. From my books; that was the Yak-3's best high altitude performance range, and anything higher would probably get the Yak-3 into trouble. Farther down, like sea level down, I'm sure you could get some pretty good speed from the VK-105PF-2, but I haven't tested it myself on BoP. I think the Yak-3 along with all the other planes are a bit inaccurate here and there.

For example, the Yak-3 did not have a ring like the early Yak-1, 7, 9's did.

Picture of a REAL Yak-3 cockpit, everything where it should be. The picture is also in my books, but I found it online so it was easier.

Thanks Ace, it's good that you arrived when you did. Though you have proven our figures wrong, I think the three of us can agree that our BoP planes are much too slow at least at sea level.

The Spitfire IX in-game has a larger rudder, suggesting it's a late-built model, most of which were equipped with the Merlin 66 engine. Spitfire LF IX (one's with the Merlin 66) could usually pass 330 mph at sea level. You'll notice that isn't anywhere near possible in BoP. If our Mk.IX is indeed modeled after the first Mk.IX's that entered service with the Merlin 61 in 1942, I should still have little problem passing at the VERY least 310 mph without WEP, which again, does not happen. Of course, since all the planes are a little too slow, that shouldnt be much of a problem. The problem arises when the Hurricane behind you reaches 200 mph the same time as your Spitfire IX when you both started at 170 mph. Acceleration is a very important advantage that some fighters have over others that simply allows for a domnant energy fight.

kozzm0, Lift cannot be produced without drag. When the slats are deployed, they do indeed produce much drag, but that's not a problem when you're pulling alpha trying to out turn someone.

I know there has to be drag... I was thinking about how the slats improve performance by "delaying airflow separation," it seems like that would also decrease the difference in pressure on the leading edge. Anyhow they worked, I guess

you've been drafted by team USSR, btw... check the battle for europe thread

Recently I was training with an la7 and my engine was hit so I headed back to land at 55% power... and noticed I was doing over 600. No lack of power in that model.
